| 摘 要： | 本文用组态相互作用理论研究Ｈｅ原子的非谐振光致电离。本文详细分析双重激发自电离态，考察第一电离阈值附近的非谐振谱，计算非谐振区的ｅ－Ｈｅ＋，１，３Ｐ散射位相移动及来自ｌｓｎｓ１，３Ｓ的光致电离截面，本文计算结果与实验观测值及现有的理论结果相比较，相当符合。

| Abstract: | We present the nonresonant photoionization of the He atom using a simple configuration-interaction approach. The double excited autoionization states and the nonresonantspectra near the first ionization threshold are examined in detail. The e-He+, 1,3P scattering phase shifts and the photoionization cross section from is ns1.3S are calculated. The excellent agreement between the present calculation and other existing theoretical and experimental results are obtained. |
